As the name implies, One-Chord Grooves use just one chord for an entire verse and/or chorus of a song. These progressions are not very common. Songwriters have used various unique bass lines, guitar riffs, and driving rhythms as well as chord quality substitutions to overcome the inevitable boredom of a single chord verse or chorus. The "I" and the "Im" chords are most commonly used. The sixteen-bar verse progression to Steely Dan's 1972 hit Do It Again is shown below.
